Rulmenţii pentru arborii principali de maşini-unelte au toleranţe de fabricaţie îngustate. Sunt adecvaţi în special pentru suspensii cu cerinţe maxime la precizia de ghidare şi la turaţie.

Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed versions.

Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and speed capacity. They have proved highly suitable for the bearing arrangements of spindles in machine tools.
